All, I'm trying to use ElasticSearch on the backend to do search within my data. I'm using elasticsearch-0.18.5 jar in my libraries. I have lucene-cide-3.5.0.jar as well since I was trying lucene before. But I'm getting an error while creating a code. Here is a sample of my code and the error I get: ``` Node node = NodeBuilder.nodeBuilder().node(); // Gives me an exception error after this line Client client = node.client(); ``` Exception: java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z at org.elasticsearch.common.logging.log4j.Log4jESLogger.isTraceEnabled(Log4jESLogger.java:57) at org.elasticsearch.common.logging.support.AbstractESLogger.trace(AbstractESLogger.java:48) at org.elasticsearch.monitor.MonitorModule.configure(MonitorModule.java:86) at org.elasticsearch.common.inject.AbstractModule.configure(AbstractModule.java:59) at org.elasticsearch.common.inject.spi.Elements$RecordingBinder.install(Elements.java:210) at org.elasticsearch.common.inject.spi.Elements.getElements(Elements.java:91) at org.elasticsearch.common.inject.InjectorShell$Builder.build(InjectorShell.java:142) at org.elasticsearch.common.inject.InjectorBuilder.build(InjectorBuilder.java:103) at org.elasticsearch.common.inject.Guice.createInjector(Guice.java:93) at org.elasticsearch.common.inject.Guice.createInjector(Guice.java:70) at org.elasticsearch.common.inject.ModulesBuilder.createInjector(ModulesBuilder.java:58) at org.elasticsearch.node.internal.InternalNode.(InternalNode.java:148) at org.elasticsearch.node.NodeBuilder.build(NodeBuilder.java:159) at org.elasticsearch.node.NodeBuilder.node(NodeBuilder.java:166) Any suggestions? ---

You have to match the slf4j and the log4j version loaded in your classloader. Looks like the log4j you are using is too old for the slf4j version that ES brings.

ES does not come with slf4j, I think the problem is just an old log4j jar.
